Gwen is currently in a weak state, requiring high mastery. As a pro-play champion, she's prone to continued nerfs.
Riftmaker and Ghost are essential. She snowballs hard with an early lead and excels at shredding tanks in the mid-late game.
She struggles against strong early-game champions like Volibear, Darius, and Pantheon, but holds an advantage against some bruisers like Mordekaiser and Renekton.
